Maine Department of Public Safety spokesman Steve McCausland said the invasion occurred on Tuesday, March 5.

According to McCausland, at 1 a.m., troopers responded to a report of a home invasion on Wanning Road in Unity, where three men had forced their way into a 72-year-old woman's home.

The victim woke up to find the men dressed in dark clothing in her bedroom, demanding drugs and money, according to McCausland. The woman was not injured and was able to call 911 after the men stole some money and her cellphone.

Troopers said the men had bought gloves, bandanas and zip ties before the robbery, but the woman was not tied up.

McCausland said authorities arrested the following people and took them to the Waldo County Jail:

Nineteen-year-old Paige Lanctot of Skowhegan. She faces a charge of criminal conspiracy. She is free on $1,000 bail.

Eighteen-year-old Alexander Salvas of Skowhegan and 22-year-old Bryan Gower of Waterville. Both are charged with burglary and robbery and are being held in lieu of $5,000 bail.

According to McCausland, authorities arrested Lanctot and Salvas on Tuesday in Skowhegan and authorities took Gower into custody in Waterville on Friday.

Authorities said they are still looking for 27-year-old Danny Green, who is from the Waterville area. McCausland said he is facing charges of robbery and burglary.

According to McCausland, Green is a transient. Anyone with information about Green and where he might be is asked to contact state police in Augusta at 624-7076.
